Current Trends for Delirium Screening within the Emergency Department

Area of Science:

• Geriatric Medicine
• Emergency Medicine
• Neurology

Background:

• Delirium is an acute neurological disorder impacting attention and cognition, posing significant morbidity and mortality risks for older adults (>65 years).
• It is frequently undiagnosed in the Emergency Department (ED) setting despite its prevalence among elderly patients.

Purpose of the Study:

• To review and summarize current evidence on delirium screening tools specifically for the Emergency Department (ED) population.
• To highlight the need for validated instruments to improve early detection and management of delirium in older ED patients.

Main Methods:

• A comprehensive literature review was conducted, including randomized controlled trials, clinical studies, and observational research.
• The review focused on studies published in recent years, examining the validation and applicability of delirium screening tools in emergency settings.

Main Results:

• Most existing delirium screening tools, validated for Intensive Care Units (ICUs) or geriatric departments, lack validation within the ED context.
• The optimal timing and format for delirium assessment in older adults within the ED remain undefined.

Conclusions:

• Delirium is a prevalent and critical condition that emergency physicians must address daily.
• Further research is essential to develop and validate effective screening tools and protocols for delirium in the ED to enhance patient outcomes.
